The Maryland State Highway Administration is about halfway through a project that is rebuilding the traffic signals and making other improvements at six Colesville Road intersections in downtown Silver Spring.

The new equipment includes pedestrian countdown signals. Two of the intersections, at Wayne Avenue and Thayer Avenue are pretty much done, but the power has not yet been turned on.

Four others are partially done, including work on the sidewalks. They are at Sligo Avenue, East-West Highway, Silver Spring Avenue and Bonifant Street. Most should be done by the end of the year, and the entire project completed by late spring, said David Buck, a spokesman for the highway administration.
